Lose Internet Connection After Sleep Mode/Standby/Hibernate

I recently purchased a new HP Pavilion Elite e9105z CTO Desktop and migrated from Win XP to Vista Home Premium x64, with a NVIDIA nForce 10/100 Mbps Ethernet Controller.  Whenever I come out of sleep- or standby-mode, I lose my Internet connection and have to either reboot my system or run the Windows Network Diagnostics to repair the network adapter settings.

I have tried several remedies available from the Internet; but unfortunately, nothing has resulted in a permanent solution.  I contacted my ISP provider (Mediacom) to ask if there was/is an issue with the firmware used to support my SBV5220 cable modem (e.g., non-compatibility with Vista) and they said there isn't.  To date, I've:

  1. Reinstalled network card driver.
  2. Checked and reset power options with USB CDC.
  3. Applied update for Windows Vista (Default Gateway Setting is Lost ) for x64-based Systems (KB933872)--received response that update does not apply to system.
  4. Reset IP configuration via Cmd line.
  5. Under the Power Management tab, unchecked the box that turns off the adapter when power saving kicks in.

I access the computer several times a day and having to reset Internet connections has become extremely aggravating.  I hope there is a solution.  Thank you in advance for your assistance.

Returning from a 3-week vacation, during which my desktop was off, my local internet connection would no longer come active when it came out of hibernation.  The wireless functioned, but the local connection would not work unless I physically unplugged the cable from the router (Netgear) and reinserted it.

After several days of frustration I went into Device Manager, unchecked the  ethernet adapter option "allow the computer to turn off this device".

This seems to have cleared up the problem, at least so far...

    I had the same problem in Windows 10 up until today and the only way I could resolve it was by resetting TCPIP with the various commands mentioned elsewhere on the Microsoft forums (netsh and ipconfig etc).  The suggestions involving disabling Energy Efficient Ethernet settings on my NIC did not resolve the problem.

    I have a broadband modem/router as the main networking device which my desktop PC is connected to via Ethernet. Wireless networking devices on the PC are disabled.

    I then have two switches to get my Ethernet cables to the other end of my house where I have a Netgear wireless router which was connected to one of the switches via one of it's 4 LAN ports

    I was able to determine via the registry editor (regedit) that the default gateway on my desktop was changing to the MAC address of the wireless router when waking from sleep.

    I thought I would have to alter the configuration of the wireless router when I looked at the back and saw it had a WAN port.  I switched the cable from a LAN port to the WAN port and the problem seems to be fixed.  I deleted the unnecessary network entries from the registry and they have not come back.

    So, my problem is resolved, but I don't understand why Windows would change the default gateway to the wireless router when it had to go through the modem/router to find the wireless router?
